ABSTRACT:
A bullet and method of making the bullet is disclosed. The bullet comprises an outer jacket of copper base material and an inner core of lead. The jacket includes a base portion and an ogive shaped cylindrical portion. The base portion has a higher yield point than the cylindrical portion so that the base portion will remain intact after impact with a game animal while the cylindrical section splits longitudinally and expands as the bullet travels into the target with a minimum in weight reduction. The method of making the bullet includes work hardening the base portion more than the cylindrical portion to obtain the higher yield strength.
